图示偏振光显微镜下的正常骨松质，可见突出的板层状结构。

Here is normal cancellous bone as seen under polarized light microscopy, which highlights the lamellar structure.

得到了在不同情况下出现的光子反聚束、光场的亚泊松行为以及光场的挤压性质。

We obtain antibunching of photons. the sub-poissonian behaviour of optical fields and their squeezing properties in different cases.

证明了亚泊松泵浦及原子的相干性可使多单光子双稳态的光场噪声降低，但不能产生光场的压缩效应。

We show that the refular pumping statistics and atomic coherences can reduce the field noise of multiple one photon optical bistability, but can not result in field squeezing from an ordinary vacuum.
